Origins
Protocol5.com
The older site described Protocol5 as a mathematical experiment by Long Term Software Solutions, Inc., created and maintained by Michael Kappel, MCPD. The current architecture keeps that mathematics history while adding UAI-1 for .NET implementation as a separate Protocol5 implementation surface.
Technology
Then and now
The current version keeps the math-provider core, adds stronger testing, hosts a Blazor calculator shell, and publishes UAI-1 for .NET package links, compatibility mirrors, and implementation notes as a separate Protocol5 section.
Intent
Distinct sections with clear authority
Protocol5 exists to publish numeric tools, package downloads, and compatibility aids clearly. UAI standards truth belongs on UAIX.org; Protocol5 supports implementers with .NET packages, samples, workbench tools, and local mirrors.
